DM2E‘s EDM Application Profile Data Model, Mappings and Documentation

Berlin School of Library and Information Science, Humboldt-Universität zu Berlin Presentation at the Meeting of National Europeana Partners

Berlin, 08.11.2013

Introducing the DM2E Project

Digitised Manuscripts to Europeana (DM2E) • EU-funded Europeana satelite project • Duration: Three years (2012 – 2015) • Partners from Germany, Austria, Norway, Greece, UK and Italy • Primary aims: To enable as many content providers as possible

to get their data into Europeana and to stimulate the creation of new tools and services for reuse of Europeana data in the Digital Humanities

IBI at the Humboldt-Universität zu Berlin • Coordinates the project • Is further involved in modeling and in evolving the technical

infrastructure

DM2E: Key Aspects

• Content – Input formats: TEI, MAB2,

MARC, EAD, METS/MODS Database content

– Mappings to the DM2E model

• Technology – Mapping infrastructure – Tools for scholars

• Community Building – Hackathons – Workshops

DM2E Model DM2E‘s EDM Application Profile:

Specialising the EDM


Domain: Manuscripts Target groups: DM2Es data providers, Digital Humanities community First test data: TEI transcriptions of Wittgensteins manuscripts from the University of Bergen

Specialising the EDM II

Creation of the DM2E model that specialises the EDM


Data analysis

Production of rich

mappings

Creation of a first model

Integration of provider feedback

DM2E model

The DM2E Model

• Namespaces: – dm2e: <http://onto.dm2e.eu/schemas/dm2e/1.0/> .

– dm2edata: <http://data.dm2e.eu/data/> .

• Additional external vocabularies – Bibo, FaBiO, PROVIVO, VoID

• Modelling analogue to EDM – Extensive use of properties instead of classes

E.g., 52 new properties for edm:ProvidedCHO – If possible: direct reuse of external vocabularies

DM2E Model: Property Extensions


dcterms:creator

dm2e:composer

dm2e:painter

dm2e:writer

pro:author

pro:illustrator

Example: Adding new properties as subproperties for dcterms:creator.

Mappings From Provider Formats to DM2E:

Mappings

1. Mint – Mapping tool by the National

Technical University of Athens – Mapping via Drag and Drop


2. Coded Mappings

– E.g. XSLT with Oxygen – Can be based on Mint Exports

Example Mapping I: XML TEI 5 Input Polytechnisches Journal


Example Mapping II: RDF Output Polytechnisches Journal


Example Mapping III: RDF Output Polytechnisches Journal


Ingestion Workflow


The Result: Linked Data


Documentation Different Ways of

Documentation

The DM2E model is documented in three different ways: 1. For human readers as a PDF manual. 2. For offline usage as a separate OWL file. 3. Machine-readable and online via Neologism.

→ The descriptions in all representations are equivalent. Advantages and Disadvantages:

1. PDF: Not useful for tools but easy to read for humans. 2. OWL-File: Can easily be produced and read but the entities

are not Web-referenceable. 3. Neologism: RDF and HTML representation of entities but

shows only entities within one Namespace.


Documentation: PDF and OWL

The PDF and the OWL representations can be accessed via the project‘s website:

dm2e.eu/document/#DM2EModelSpecification


Documentation: Neologism

• Vocabulary publishing platform

• Based on Drupal • Upload of

ontologies (RDF, OWL)

• Creation of new classes or properties


onto.dm2e.eu/dm2e

Next Steps

• Finalising the DM2E model – Open issues: uncertain timespans or creators – Consistency check – Update to the newest EDM version

• Analysis of the mapped data

– Leading to further model optimisations
